This paper presents a new method for representing SSR(Subsynchronous Resonanace) Phenomena using 3-D computer graphics animation. A virtual power system simulation environment was made for simulation and visualization of SSR phenomena. It is anticipated that the proposed method would be helpful for the operator training as well as power system education.

Computer graphic where the most useful and effective production methods are used for animation or films has expanded into actors' performance beyond object expression, background expression and special effect. Unlike 2D drawing software focusing on user's sense, 3D mainly depends on hardware performance and software functions. Therefore, for 3D users, learning 3D functions is directly related to new expression, and quick learning and effective representation are keys to productivity growth in animation industry. In line with industrial needs, basic 3D animation software training is provided in school. Unfortunately, however, many problems such as lack of professional instructors, time allocation and education environment prevent various 3D animation software from being taught. Moreover, functional use does not live up to industrial rapid trends. In order to improve effects of software functional education in restricted education fields, this research aims to find out what functions of 3D animation software are used in industries, what are those function used for, and how schools provide 3D animation software training.

The informatization of Korea is accompanied by the great growth of new strategic export industry, as of mobile phone or semiconductor LCD. Speaking to the situation of mobile phone, Motorola swept over the American domestic market in the beginning of 1990s, digital mobile communication as CDMA developed swiftly in Korea. In 1996, the first year's CDMA users of Samsung were merely one million, nevertheless, the world's sales in the first half of this year is up to 92 million. In this p aper I design 3D application based on J2ME and implement a freely removable 3D object which happened in a 3D scen e by receiving the keyboard response of mobile device with WTK (Wireless ToolKit) simulator. It contains benefits of improvement of relative speed and high-level functionality such as scene graph, keyframe animation, etc.

The article deals with the reality subject of animations. Animations are created on the basis of fantasy. Disney's introduction of the narratives and styles of live action film into the field of animation, which laid a foundation for the hyper-reality animation, has produced an unintended consequence of marginalizing other animation genres which have emphasized fantasy through free experimentations of various images. A combination of Disney's world view of hyper-reality with later-developed 3D computer animation technology has made fantastic figures and spaces much more real than the real ones, and succeeded in creating a matrix of simulacre, a world of mere copies without the original.

From the flood of various informations and images, the producer and the consumer pursue a new method of images constantly. Especially the computer graphic field has affected the images greatly, and has changed the paradigm of images. The 3D animation which is a part of the computer graphics has two general trends(namely the photorealistic rendering and the non-photorealistic rendering) as to the final image. This study overviews the photorealistic rendering and the non-photorealistic rendering by analyzing the technical side and the artistic side. Also this study presents the applicable scope and the advanced directions of the NPR.

This paper designed 3D animation in consideration of human characteristics to stimulate their interest and to be more understandable to them. It was also confirmed that, using the 3D animation contents, general people came to recognize the problem of environment pollution and developed desirable attitude and behavior for protecting the environment. Furthermore, this paper suggested the ruins original form restoration technique of the residential environment and the natural environment of Hanyang in the Joseon Dynasty period using the 3D virtual reality digital recovery techniques.

The computer has become an indispensable tool for animation works. However if you don't understand the characteristics of the computer and its software, you might not have the result satisfying your efforts. The incorrect understanding of image format sometimes causes it. Habitually image formats are selected usually for most of works but there is a distinct difference among those image formats while the efficient usages of them are different from each other. For your more efficient work therefore, you need to identify the characteristics of various kinds of image format used mostly for animation works. First I took a look at the theories of the lossy compression and lossless compression, which are two types of data compression widely used in the whole parts of computer world and the difference between bitmap method and vector method, which are respectably different in terms of the way of expressing images and finally the 24 bit true color and 8 bits alpha channel. Based on those characteristics, I have analyzed the functional difference among image formats used between various types of animation works such as 2D, 3D, composing and editing and also the benefits and weakness of them. Additionally I've proved it is wrong that the JPEG files consume a small space in computer work. In conclusion, I suggest the TIF format as the most efficient format for whatever it is editing, composing, 3D and 2D in considering capacity, function and image quality and also I'd like to recommend PSD format which has compatibility and excellent function, since the Adobe educational programs are used a lot for the school education. I hope this treatise to contribute to your right choice of image format in school education and practical works.

According to traditional 2D animation techniques, anticipation makes an animation much convincing and expressive. We present an automatic method for inserting anticipation effects to an existing facial animation. Our approach assumes that an anticipatory facial expression can be found within an existing facial animation if it is long enough. Vertices of the face model are classified into a set of components using principal components analysis directly from a given hey-framed and/or motion -captured facial animation data. The vortices in a single component will have similar directions of motion in the animation. For each component, the animation is examined to find an anticipation effect for the given facial expression. One of those anticipation effects is selected as the best anticipation effect, which preserves the topology of the face model. The best anticipation effect is automatically blended with the original facial animation while preserving the continuity and the entire duration of the animation. We show experimental results for given motion-captured and key-framed facial animations. This paper deals with a part of broad subject an application of the principles of traditional 2D animation techniques to 3D animation. We show how to incorporate anticipation into 3D facial animation. Animators can produce 3D facial animation with anticipation simply by selecting the facial expression in the animation.

The current software for creating and editing animation offers the possibility of dividing variable objects into layers. This paper suggests a method to render and edit each of right and left layer in the process of creating a 3D stereoscopic animation. It is possible to apply a variety of effects to left and right images and to adjust the gap of binocular parallax through this method so that wider variation of images and richer sense of depth can be produced. In addition, this method offers freedom of deleting and inserting an object, controlling size and position of the object and adjusting the gap of binocular parallax. Thus, new sense of depth can be obtained. This method shows the results to apply various effects on the 3D stereoscopic image and to reduce visual fatigue rather than the method to render simultaneously both of left and right layer.
